摘要
运用模糊ISODATA分类方法对我国67个城市共87条主要城市内河(包括中小型河流城市区段),选取了包括氧平衡参数、营养元素、重金属离子、油类等共12个指标进行水质污染程度的分类研究.在以上分类的基础上,选取污染超过地表水环境质量III类标准的53条城市内河计算污染分担率,对其按污染类型进行分类;并探讨了城市内河污染类型与城市产业结构之间的关系.
12 indexes including oxygen-balance parameters, nutrient elements, heavy metal ions and oils were selected,and the degree of pollution of 87 major inland rivers in 67 cities (including the sections of the inland rivers in cities) were studied using the method of classification of fuzzy ISODATA clustering analysis.Based on this classification, selecting the polluted 53 inland rivers in cities which exceeded type Ⅲ of GB3838-2002 as samples,the sharing ratio of pollution and then the classification of the rivers according to the types of pollution materials are given.At the same time, the relation between the types of pollution of the inland rivers and the structure of industry in cities was also discussed.
